A hydraulic power unit consists of components such as hydraulic pumps, electric motors for driving, oil tanks, directional valves, throttle valves, and relief valves, forming a hydraulic power supply unit or a hydraulic system that may include control valves. It supplies oil according to the required flow, pressure, and flow rate of the drive unit, suitable for various mechanical devices where the drive unit is separated from the hydraulic power unit (cylinder or motor). By connecting the hydraulic power unit to the drive unit (cylinder or motor) with oil pipes, the hydraulic system can perform various prescribed actions.

A hydraulic station is an independent hydraulic unit that supplies oil according to the requirements of the driving unit (main engine) and controls the direction, pressure, and flow of the oil. It is suitable for various hydraulic machinery where the main engine can be separated from the hydraulic unit. The motor drives the oil pump to rotate, which draws oil from the oil tank and then pumps it, converting mechanical energy into the pressure energy of hydraulic oil.
